The factory recommends that when service is performed on any BIRO SAW the servicing agency be sure that the
BIRO SAW is equipped with the most current safety features available.
MODEL 44 SAW GUIDE BARS AND SAW GUARDS
Production of the BIRO Model 44 began March 1956. All units prior to serial #4511 were equipped with a (round)
cast aluminum head. The saw guide bar measured 21½
²
and the (Item #255) SAW GUARD was the same as used
on Models 33 and 34.
The factory recommends that on all units equipped with (round) cast aluminum heads, the complete head
assembly be replaced with the current stainless steel (fabricated square) HEAD ASSEMBLY (Item #AS18005).
All units serial #4511 on were built with a fabricated (square) steel head. The saw guide bar on these units
measured 27

and is current. All units serial #4511 on are equipped with the most current safety features.
